Possible regression (assert(_adapter == NULL) failed: init'd to NULL)

[Howard Lovatt]

Using Stephen's Mac OS X builds I find that the latest build:

java (JVM) Version:
openjdk version "1.7.0-internal-fastdebug"
OpenJDK Runtime Environment (build
1.7.0-internal-fastdebug-stephen_2011_02_07_15_42-b00)

Has a problem with a method reference:

    final ActionListener al4 = Main#print( ActionEvent );

Where print is:

  private static void print( final ActionEvent notUsed ) {
    out.println( "Main.print method called" );
  }

The error I get is:

# To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc:  SuppressErrorAt=/methodOop.cpp:697
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error
(/Users/stephen/dev/java/src/mlvm/sources/hotspot/src/share/vm/oops/methodOop.cpp:697),
pid=87457, tid=4298117120
#  assert(_adapter == NULL) failed: init'd to NULL
#
# JRE version: 7.0

#

If the error at methodOop.cpp:697 is suppressed then the error is:

Exception in thread "main" java.lang.NoSuchMethodError:

        at com.sun.runtime.ProxyHelper$1.invoke(ProxyHelper.java:61)

        at lambdas.Main.methodReferences(Main.java:147)
        at lambdas.Main.main(Main.java:24)


The previous build, dated 11 Jan, is fine with this example.
